Following the simple rules and suggestions below can help you, other members, and our moderators to be happier people. Yes, truly, we will all be happier! When you create mis-catagorized, or poorly-posted quant questions, it leads to confusion and diminishes the valuable forum content. It also makes our lives stressful and disorganized. However, if you follow these 11 simple suggestions, you can expect great karma, good looks, and extra points on the GRE! If by chance that did not convince you, ignoring or breaking these rules will likely lead to removed posts, warnings, eventual bans, and a possible hair loss. Please follow the rules. Thank you!

1. Use the Search Box Before Posting.

- Before to post a new one question, is important to use this powerful tool. Otherwise, we are going to create duplicated post. Use it wisely- Forum Search

- Use the first sentence of the question or a string of words exactly as they show up in the question. You get 40 characters. Use them all to help with the search & similar topics feature!

4. Post Only one Question per Topic.

- Please do not post multiple questions in the same post as it makes timer, search, tags, and other functions irrelevant.

5. Do not Change the Question.

- It is extremely important that the integrity of the original question is maintained. Remember, every word that is included in a question is there for a reason!

6. TYPE the Question in as Text.

- Do not post pictures of questions. The only time a picture is acceptable is when a question has a diagram. If a diagram exists, make sure to always attach it using JPG/GIF/PNG formats. Do not use Word or PDF documents.

7. Indicate the OA (Official Answer)

- Use the A, B, C, D, E radio buttons and make sure you post the answer choices.

8. Post Always The Answer Choices for Math Questions

- One should always look at the answer choices before starts to solve a problem. They might often give a clue on how to approach the question.

- At least 3 tags are required: difficulty level (in your opinion), question category, and source of the question. You are welcome to use more tags as applicable. You can also TAG other people’s posts to make them more valuable.

11. Avoid Short/Useless Posts (they will be deleted) and use the Kudos Button Instead.

Another Way of Writing Fractions:How to make (a+b)/c to look like \(\frac{a+b}{c}\)Step 1: Write \frac{a+b}{c}, (note that numerator and denominator must be enclosed in { } and you must write out \frac to tell the system that it is a fraction);Step 2. Highlight the whole expression and press m button.
